Find x and y if `x((4), (-3))x+y((-2), (3))=((4), (6))`.

Find x and y if x [(4,-3)] + y [(-2,3)]= [(4,6)]

Find x and y if ((3x+4y,x-2y),(5,-3))=((2,4),(5,-3)) .

Find X and Y if 2X+Y=({:(4,4,7),(7,3,4):}) and X-2Y=({:(-3,2,1),(1,-1,2):})

Let |{:(y^(5)z^(6)(z^(3)-y^(3)),,x^(4)z^(6)(x^(3)-z^(3)),,x^(4)y^(5)(y^(3)-x^(3))),(y^(2)z^(3)(y^(6)-z^(6)),,xz^(3)(z^(6)-x^(6)) ,,xy^(2)(x^(6)-y^(6))),(y^(2)^(3)(z^(3)-y^(3)),,xz^(3)(x^(3)-z^(3)),,xy^(2)(y^(3)-x^(3))):}| " and " Delta_(2)= |{:(x,,y^(2),,z^(3)),(x^(4),,y^(5) ,,z^(6)),(x^(7),,y^(8),,z^(9)):}| .Then Delta_(1)Delta_(2) is equal to
